This invention relates to an improvement in a detachable type bookmarker and holder for said marker.

Today, many students of various books, such as the Bible, find it necessary, in connection with their study thereof,to mark certain oft-read passages, and to change these markings frequently when new passages are; to be studied. It has long been the object of various devices to provide a marker which can be readily removed from one'place in the sired to change the location of a single markthreading the holding means through each end. Further difiiculty with markers of the prior art of this general type has been that the attaching means has pulled the marker deep into the space between thev leaves until it was flush against the binding, causing a detrimental bulging of the book at the bind- Ihis bulging and distortion of the leaves at the binding causes a rapid deterioration of the book. Leaves become loosened and fall out.

It is the object of'the present invention to provide a bookmarker set having holding means which are normally in place at the top and bottom of the book binding and are not removed when changing the position of the markers, to provide a marker holding means which holds the markers away from the binding of the book and prevents injury thereto,

' markers.

to provide a marker holding means which'is V easily attached to and removed from books and when in position, forms an integral part of the book binding, to provide a mark'er holding means with the holding bar shaped to guide the marker when the leaves of the book open and close, to provide a marker shaped so as to present the minimum distortion to the leaves at their juncture with the binding, to provide a marker'which is easily flexed and removable from one place in thebook without disturbing the holding means or the positioning and security of. other The invention also includes other features and improvements which willappearin'the following description: 7 v I 7 Referring to'the drawings whichillustrate; the invention' r e 3 Fig. l is a perspective view of a book-showing the holding means, and two markers in place;

B represents a book having covers 1 attached to the bindin at the back of the book. The leaves 3 are attached to the binding. As is customary, the back 2 extends slightly above the tops of the leaves 3. 3

In certain uses to whichbooks are put, it is sometimes desirable to have as many as thirty (30) markers placed between as many selected leaves of the book. These markers 7 5 may be of thetype shown inFig. 4 or the type shown in Fig. 6. The marker 5 is -formed with a vertical portion 6 having out wardly forked ends 7 and an outwardly ex tending section 8; Attached on the outer extremity of 8 is a number or other indicating means which extends-out beyondthe edge of the leaves so as to bevisible.

The marker shown in Fig. 4 consists of the same elements as the marker shown in Fig. 6, butdifiers from it in that the vertical sec tion 6 has its two extremities bent to form parts 9. The purpose of this is to further remove the vertical section 6 from thebinderly position the vertical section 6 0f the marker-out fromthe binding. This has not been true of the prior art typeof marker holder, in whichithe tendency-of the holding means, upon the book being opened, was to draw in the vertical section 6 until it cont-actedxthe binding, .and then, when thebook was closed, the two leaves between whichthe marker was positioned, would be badly strainedat the point where they joined the binding. In many cases, :the leaves have.

become loosened and fall from the book.

The holding means by which the markers are maintained :in proper position consists of a retaining loop or bar10, positionedtoibe engaged. by the forked ends 7 of "the markers. The loop 10 is shaped to conformito the direction of movement of the forkedends 7 of the markers when the leaves of the book are shifted from closed position to an openposition', or vice 'versa. The proper shaping of the loop 10 is important, for it is preferable that at no time should the vertical section 6 of the marker be forced into harmful contact With-the binding of the boo'k when the leavesare closed. The retaining looplOis positioned slightly above the tops of .the leaves :byzmeans of .a bar 11 extending across the tops of the leaves in close contact with.

the end ofthe :binding l. It is important that the bar 11 be shaped or bent outwardly from theend of the bindingtoabout the degree of curvature assumed by the binding when the book islying open on a table. This curvature is also a gguideto the'proper shaping of the loop 10. Thecurvature. at theend of the loop 10 (will vary-somewhat, depending on the thicknessof the book, and can beeasily determined by placing'between several ofthe endzleaves themarkers 15, first observing the position of'the forked end 7 A marker retaining means, such as shown in Fig. 2, isused at each end ofthe book, and" is .maintained in position by means of-the arms 13, which may be-formed integral with the bar 11, or suitably attached thereto. .A

hook 14 is formed at the extremities of these arms 13, and a pair ofsnitableconnecting means, such as rubber bands 15, holds the two marker holders in place in the book. When the size of the book, in which the retaining means is to be used, is known by the manufacturer, the form of the device shown in Fig. 7 is preferred. In Fig. ,7 is'shown sucha marker holding means. 1

.The loop .means are identical with that shown in Fig. 2,,the only difference in this construction being that the connecting members 16 are spaced-aparta distance determined. by measuring the thickness of the pages of the'book inside the covers. The

length-of the wires16 is such that the two bars 11 will clear the tops of the leaves by thebarest'marg-in. =Once in;place,-it:isseldom ever: removed-until the bookwears out. 7

The modification of holding'means shown inT'F-ig'. 3 differs from thatshown in Fig.2

only in that theretaining loop 100: issoi formed was ,to occupy a position farther removed f-rom-the tops of thewleaves of the book. Thislmodification is intended-.particue larly for use withthe marker shownin Fig.

4, z'and has particular advantage in thosecases where itis desired to cause a minimum distortion of the lea-vesat or near the binding. The retaining loop 10a, is raised above the .leaves sufliciently that when the forked ends 7 of the marker shown in Fig.4 are in place on the loop =1Oa,=the .lowerpart of the extensions 9 :of the. marker. will avoid contact withthe tops of theleaves. p

By :employing the invention described herein, it is possible for a'student to I quickly and easily change'the.position'of'the various markers without removing the marker holding means, and each marker is removed and placedin its-new position without disturblng any other marker or ;markers. that maybe i111 place.

To change the position of a marker, it is grasped by the fingers, as shown in Fig. The vertical section-6 being'flexible, a slight upward or downward movement of the-marker'will disengage 'oneofthe forked -:ends '7 from the-retaining loop 10. 'Movementrinthe opposite direction will release the other forkedend and the marker is free to be placed in'a new position in'the book. In replacing them rker, the operations ust described are reversed. One forked end is placed over the lower or .upper retaining loop.10, and by means ofthe fingers grasping themarken'the vertical part 6 is buckled slightly, and the forked end 7 is slipped into place on the other retaining loop 10.

An advantage-of the. type marker shown in Fig 4; is that in changing position, instead-of having the finger grasp the barb of the marker, the fingercanienga'ge the ,upright portion6, at, or near, the bent portion 9. It iscontemplated that instead of wire, the hOIdGIsmay-be made of other materials,such

as stampings or castings, from metal, bakelite, etc.

Having thus described my invention, what I claim and desire to secure by LettersPatent is 1. In a bookmarker set, the combination of a marker comprising a flexible section shaped to extend along the inside edge of the page adjacent the binding, having outwardly forked ends and a part extending out from the flexible section to beyond the edge of the sheet to indicate the position of the marker and a holder at each end of the book for positioning said marker in the book comprising a retaining loop positioned to be engaged by said forked ends and shaped to follow the curve normally taken by said forked ends when the book is opened and closed, a bar fastened to said loop and resting on the tops of the leaves, and means to connect the holders.

2. In a bookmarker set, the combination of a marker comprising a flexible section shaped to extend parallel to the inside 'edge of the page but spaced out slightly from the bind ing so as not to bulge the book at that point, having outwardly forked ends and a part extending out from the flexible section to beyond the edge of the sheet to indicate the position of the marker, and a holder at each end of the book for positioning said marker in the book comprising a retaining loop positioned to be engaged by said forked ends and shaped to follow the curve normally taken by said forked ends when the book is opened and closed, a bar fastened to said loop and resting on the tops of the leaves, and means to connect the holders.

3. In a bookmarker set, the combination of a marker comprising a flexible section having outwardly forked ends and a part extending out to indicate the position of the marker, and a holder at each end of the book for positioning said marker in the book comprising a retaining loop positioned to be engaged by said forked ends, a bar fastened to said loop and resting on the tops of the leaves and means to connect the holders.

4:. Abookmarkerholder,comprisingaholder at each end of the book for positioning markers in the book, having a retaining loop positioned to be engaged by the forked ends of a marker and shaped to follow the curve normally taken by said forked ends when the book is opened and closed, a bar fastened to said loop and resting on the tops of the of the leaves, and resilient means to connect the holders.
